In the Caribbean climate, dust, sea salt, and bird droppings quickly accumulate on the surface of solar panels. These deposits limit the capture of sunlight and can reduce production by up to 20%.

Regular maintenance therefore ensures optimal efficiency and stable solar power production throughout the year.

​

How often should you clean your solar panels?

​

In Saint Martin, it is recommended that you:

​

Clean your solar panels 2 to 3 times a year, ideally at the end of the dry season and after heavy tropical rains.

Visually check them every month for dirt, leaves, or bird droppings.

This simple monitoring helps maintain the performance of your photovoltaic system and ensure continuous production, even in a humid climate.
​

Recommended maintenance method

​

• Solar panels should always be cleaned gently to avoid damaging the protective coating. Here is the recommended method:

• Use clean water or slightly soapy water, without harsh chemicals.

• Use a soft sponge or squeegee to scrub the surface.

• Avoid high-pressure cleaners and hard brushes.

 

If possible, rinse with demineralized water to prevent limescale marks after drying.
